Location: Barcelona (Hybrid) Type: Full-time

Get to know us:

Started in 2016, Frekuent is now the all-in-one payment and loyalty platform for unattended environments — 500+ clients, 100M+ transactions a year, 2.5M+ users across Spain, France, Italy, Portugal, and Singapore. We turn one-time buyers into lifetime clients with cashless, contactless, effortless payments: less friction, more reasons to come back.

2026 has been our biggest year yet — we've hyperscaled from 40 to 100+ people, with more hires on the way, and closed a €6M funding round to fuel what's next.

And we're just getting started — our goal is to become the default payment and loyalty layer behind every unattended transaction, everywhere.

Why this role exists:

At Frekuent, we don't build backend systems for their own sake — we build the engine behind products people actually use. You'll join a lean, senior product engineering team where ideas move from a Slack thread to production in days, not quarters,



and where every tool at your disposal — including the AI ones we build with daily — is treated as leverage, not overhead.

If you've outgrown "ticket-taking" backend work and want to be in the room when a feature gets conceived, not just when it gets assigned to you, this is that room.

What you'll actually do:
- Own features end-to-end: architecture, implementation, release, and the metrics that tell you whether it worked.
- Build and scale the APIs and services that power our product suite, primarily in JavaScript and Python.
- Use AI-assisted development as a default part of your workflow — we optimize for shipping quality code fast, not typing it manually.
- Help design and integrate AI-powered features into our product — from LLM-backed workflows to smarter automation — alongside our Product and Data teams.
- Do real code review and architectural sparring with people who'll push back on your ideas (and will expect you to push back on theirs).
